Anyone know anything about this amp? Mine seems to have a power supply out. The unit wont come on at all. But I cant seem to find parts for it.

this is a picture of the amp in question http://cgi.ebay.com/1976-Infinity-DS...QQcmdZViewItem

I have the matching preamp. But I'm tackling one thing at a time.

First the Hafler, which I was able to fix with the help from you guys. Now this amp. But I just dont know much about it. it was given to me along witht the hafler amp and the matching Infinity preamp.

If I remember correctly, I think the designer (John Ulrick)of the Infinity Digital Amp now design the Spectron Amps. I could be wrong, but you can check with Spectron.

Default Infinity SWA and Bel Canto Tripath Class T

Hello - Infinity SWA parts hard to find. John Ulrich at Spectron may be able to help.

What exactly is wrong with the power supply? It may be able to be repaired. I am currently seeking SWAs for spares. I found this forum and your post while searching for SWAs on the Internet. Please post if you decide to get out of it or if you have narrowed down what the problem is.

BTW - Recently heard the 1000 WATT Bel Canto monobloc using Tripath Class T digital switching technology. The Bel Canto has me rethinking Class D.

Cool Searching for an Infinity DSP Class D Amp

I am searching for the Amp. I have the Pre-Amp which I have faithfully had working for nearly 20 years. Looking for the matching Amp if anybody knows where I could find one, or if somebody would like to part with theirs.
